Simulation research on safety verification of 60Co transportation package

Abstract

Radioactive Material Transport safety is an important branch of nuclear safety. In the safety evaluation for radioactive material transport package, the combination of experiment and simulation is often used. This paper studied the finite element simulation of a kind of 60Co source transport container. The situation of the package experiment and the finite element simulation method were introduced. Several different material models were used to simulate and their results were compare with the experimental data. The results showed that all the calculations were conservative and the bilinear hardening model was better for wood while bilinear hardening with failure strain model for steel. The feasibility of finite element simulation and the importance of material model were illustrated. Finally, some direction of the next step for finite element simulation was discussed.
